Deprecated comment.

I believe the hiera backend `module_data` has been introduced in 0.1 and then dropped again in 0.2 (I don't know why exactly).

Is this correct ?

Anyhow, there is no `data` directory anymore. Please update the docs. I am not sure I can really trust any comment now ?

Adjust integers to strings.

As part of merging #501, default values for config.pp were integers. However,
many of the current logic expects to see strings for many values. This commit
fixes things up while the validation logic can be adjusted to take account
integer.
